A spokesperson told Channel 11 Public Safety is preparing for all possibilities with Rosfeld's upcoming trial, including a repeat of what happened last summer: thousands of people protesting outside of the courthouse and across Pittsburgh.

A police spokesperson said the preparations are for "...inconveniences similar to what Pittsburgh experienced last summer."

Emergency management is meeting with businesses to ensure safety during the trial.

"We didn’t experience any type of disturbance when they marched through here, it was more of a peaceful protest," said Bobby Hornik, manager of City Works in Market Square. "Obviously if it turns violent, we don’t want that."

Protests happened all over the area, from Market Square to shutting down the Parkway.

Because of that, the city of Pittsburgh announced new guidelines for demonstrations. Protestors cannot:

Block hospitals, tunnels or bridges

Shut down important intersections at any time

Certain intersections during morning and evening rush hours

The meeting between emergency management and downtown businesses is not open to the public.

Pittsburgh's public safety director told Channel 11's Rick Earle that there will also be several road closures around the Allegheny County courthouse once the trial gets underway.

The sidewalks around the courthouse building will remain open.
